Here are the assembled parts.  One set has been worked over and polished and the other hasn't been touched.

The face of the hammer that rides against the bottom of the bolt before and after polishing.  By removing the machine marks it cycles smoother, with the other polishing as well my trigger groups will run on some of the slowest sub sonic ammunition on the market.

The pivot end of the hammer that rides on top of the sear, before and after polishing.

The top of the disconnector before and after polishing.  As the hammer rides on this as the bolt travels rearward I polish it as well.

The top of the sear that the hammer rotates against as the gun cycles, before and after polishing.

Bottom side of the sear.  I only need to polish the very end of it where the disconnector contacts the sear but it is easier just to polish the whole flat area.  This is done to allow for a smoother resetting of the disconnector.

The end of the sear before and after polishing.  I do this to allow the disconnector to reset smoother and help cut down on the chances that the disconnector will not reset if the trigger rebound spring is too light.  Other modifications are required but I will not go into them here as I do those for my trigger jobs I sell.

Finally the trigger plunger is re-radiused and polished for a much smoother trigger pull.

As you can see I do a lot of polishing when I do a trigger job and most of it is done by hand with diamond hones and assorted grit papers.  All of this work along with a few other things I do allow for a nice crisp 2.25 to 2.5 pound trigger pull with factory parts and you might see why I charge $100 for a trigger job as it takes about 7 to 8 hours from start to finish.  If you are interested in one of my trigger groups feel free to contact me for more details.
